I noticed in the html of my router this parameter:



form.addParameter('Password', base64encode(SHA256(Password.value)));



So when I type in the password passw I get this via sslstrip:



2018-09-25 21:13:31,605 POST Data (192.168.1.1):
Username=acc&Password=ZTQ1ZDkwOTU3ZWVjNzM4NzcyNmM2YTFiMTc0ZGE3YjU2NmEyNGZmNGNiMDYwZGNiY2RmZWJiOTMxYTkzZmZlMw%3D%3D


Is this hash easy to crack via bruteforce/dictionary? I am still a beginner, but that looks like double encryption to me.
Also, is there some faster way of getting this password than cracking it?

          It's a base64 unsalted sha256 hash. It's not double encryption, but a not needed encoding.



          An unsalted hash means it's trivial to just search the hash on Google and probably it will find the result.

            I meant "is trivial to search", not to find the password. But to bruteforce SHA256 using any bitcoin ASIC is trivial too. A Dragonmint 16T can do 16TH/s and would bruteforce a 12 chars alphanumeric password in less than 100 hours. A 8 chars alphanumeric would fail in a tenth of a second...

          • Sure a Dragonmint is fast and specialized hardware. That is why using SHA256 is not secure for passwords, what is needed is a slow method such as PBKDF2, Argon2i or comparable methods, these are slow and should be used with parameters to require about 100ms or CPU time and additionally Argon2i requires substantial memory as well. Try e88f244abd61582387cc2afc0476e112550f24395cdf338ed7ad7deace2e6ebe, it is a the SHA-256 hash of a 12 character password.
